IM BEING TIMED You have four vehicles, all driving at the same velocity side-by-side on a four-lane highway. They are a fully-loaded truck, an empty truck, a midsize van, and a small car. If all the vehicles brake at the same time because there is a collision ahead, which one will come to a complete stop FIRST?

Group of answer choices

the fully-loaded truck

the midsize van

the empty truck

the small car

Which object is most likely represented by a dot?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

A17,250 kg rocket is pushed with a thrust of 6,450,284 n. what is the acceleration of the rocket?
